Wireless auto chargers with touch clamp

Touch clamp

— a rather peculiar automated kind of mechanical clamp. The design of such a device provides for a sensor that determines the approach of a human hand and controls the jaws of the clamp. When such a sensor is triggered, the jaws diverge for a couple of seconds, and then shrink back — this allows you to install or remove the smartphone with maximum ease, without unnecessary movements. At the same time, touch clamps, unlike magnetic ones, have no restrictions on the material from which the smartphone case is made. The disadvantages of such systems include the relatively high cost and the need for power supply for full-fledged operation (although, usually, the device can be removed even when the power is off).
